What is 45 Boötis
45 Boötis is one of the rare relatively close neighbours in this small group: about sixty-four light-years away, an F-type star burning slightly hotter than the Sun and pulsing with a characteristic yellow-white. It lies inside the Herdsman, near the orange blaze of Arcturus. Its light takes only a couple of human generations to reach us —close, in cosmic terms.
Where it is and when to see it
45 Boötis lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is April: the Sun sits at the opposite point of the sky and the star culminates around midnight. How high it climbs above the horizon depends on the latitude you watch from.

The signature wall
Stelvia's sky works like a signature wall: anyone can leave their name and a message on a real star, and that signature goes up on the map for everyone to read. Signing is free.
A signature without a lock can be replaced by someone else's. The lock makes the signature permanent and lets you choose a symbolic name for the star, always shown next to the star's catalogue identifier. How the lock works

A public signature from a real person. The chosen name is a symbolic denomination within Stelvia, with no official standing or IAU recognition: the sky is not for sale and belongs to no one.
